I've had this mixer for two years+ and I've never any had problems with the Faders but as time flew by, they have been collecting so much dust to the point where my Fader started to bleed and Blowing it with air wasn't making a difference so I had to go in(pause)... that seamed to do the trick and with that I decided to clean the level Faders too. The above video is just a demonstration of how I did it.
